Re: o-320 STC for Colt
Thanks guys! Now I'll start looking for a core to major. Would appreciate any input from someone experienced with the WagAero STC package. Also, any recommendation about the 150 vs 160 hp.

Re: o-320 STC for Colt
Gilbert would have more current info there, I am curious to if the performance is very noticeable between the 150 and 160?
I believe with the 150 you can use alcohol free auto gas and not with the higher compression 160. I like the 150 but haven't flown a 160hp, maybe Gilbert kept the same prop when he converted from the 150 to 160 and can let us know. You can probably cruise at a bit of a lower power setting at the same speed with the 160hp and save fuel maybe.. or go a couple knots faster if needed and burn more gas. I am interested if there was a very noticeable climb performance gain?

Re: o-320 STC for Colt
Anyone know offhand if the 108 prop is useable for the conversion? If not could be a big cost driver.

Re: o-320 STC for Colt
Check the type cert data for the 22-150, lists what you can use and can't. The stc will list as well, but its not available to download from the faa stc page, use to be able to download a pdf of the stc. Call wag and ask them to sent you a generic copy.

M74DM with an O-320, M76AM with an O-235. Stock Colt prop isn't approved with either a 150 or 160 engine.

The Peterson STC covers the 160 hp ethanol free premium auto gas.

Re: o-320 STC for Colt
WagAero was kind enough to provide installation instructions. Fairly generic. My research so far indicates the only the O-320-A2A or A2B varients are eligable for the upgrade. Anyone know if one is preferred over the other?

Re: o-320 STC for Colt
I would look at the thread linked on the O-320 upgrade and the type certificate data sheet on the O-320. Any A series will work and the B can be converted. The TCDS will tell you the differences and they are easily modified to the configuration you need.
